A water wash is also known as a

• A. Water flush
• B. Desalination bath
• C. Desalination wash
• D. Desorption wash

Answer: (C)

A water wash cleans internal turbine passages by spraying water (often demineralized) to dissolve and flush away deposits such as minerals, carbon, and other contaminants that build up on compressor blades and passages. Desalination wash is the term used because the goal is to remove mineral salts from those surfaces, restoring airflow and performance just as desalination removes salts from water. Other terms don’t fit the intended purpose: a water flush is a more general flushing, a desalination bath implies soaking rather than spraying for cleaning, and a desorption wash describes removing substances by desorption, which isn’t the typical cleaning action in this procedure.
